A case of amyloid tumor of the stomach.

A 68-year-old female was admitted to hospital with a 5 month history of epigastric distress. Radiological and gastrofiberscopic examinations revealed a tumor of the stomach which was strongly suggestive of gastric carcinoma. Microscopic examination of the removed stomach, however, revealed no tumors in the stomach, but instead, there a localized amyloidosis was found in the antrum, the patient died of hepatic failure 10 months after the operation. Autopsy demonstrated no evidence of systemic deposit of amyloid substance. The amyloid tumor of the stomach is rare, and the present case is believed to be the fifth of the reported cases of this lesion and, at the same time, the first case in which the solitary nature of amyloidosis was verified at autopsy.
